pectus tawny. Abdomen tawny, suffused with light ochreous towards 
base, suffused with greyish-fuscous from beyond base to before apex 
above; two longitudinal yellowish-white pleural spots towards base. Legs 
tawny, anterior leg infuscated, tarsus becoming blackish-fuscous towards 
apex; median femur whitish-yellow laterally except above, posterior leg 
light fuscous-grey. Fore wing cleft from beyond 2 / 3 ; first segment with 
costa gently curved, termen subconcave, anal angle distinct; second 
segment spatulate, termen rounded, tomus rounded, prominent. Tawny, 
becoming brownish -fuscous beyond base of cleft ; costa with a broad dark 
coffee-brown attenuated streak reaching below upper edge of cell, lower 
edge suffused ; discal half of wing irrorated with white from base of wing 
to base of cleft ; this irroration narrowly extending along dorsum of first 
segment, dilated into a wedge-shaped area before tornus, further extending 
along costa of second segment, also occupying apical third of this segment, 
but not reaching tornus; a subcostal row of conspicuous irregular white 
dots along dark costal streak from beyond base of wing to before base of 
cleft; a faint subtrapezoid tawny -fuscous spot, rather paler than sur- 
rounding ground colour, running across first segment beyond its base and 
interrupting dark costal streak; this spot slightly irrorated with white on 
anterior half except on costa; an ill-defined narrow dark-coffee-brown line 
along dorsum of first segment. Cilia of first segment along costa and in 
apex dark coffee-brown, along termen and in tornus rather dark fuscous, 
with basal half ochreous-whitish except in tornus, along dorsum tawny, 
mixed with a few whitish basal scales posteriorly; cilia of second segment 
tawny, along costa irrorated with whitish, and with a dark coffee-brown 
antemedian fascia, interrupted so as to form rather isolated spots: a 
small spot on costa before apex, and larger spots in apex, and opposite 
middle of termen; dark grey cloudy spots: before, and in tornus; tornal 
cilia suffused with grey except along base; cilia along dorsum of wing 
rather light tawny. Hind wing rather dark brown w r ith purplish tinge, 
basal half of third segment suffused with ochreous-tawny. Cilia rather 
dark fuscous with brassy reflections, along basal half of dorsum of third 
segment with an irregular series of minute dark scales along base.

obtusely pointed, with a tooth on ventral edge, sacculus simple, moderately 
constricted before top. Juxta with a double furca: upper lobes slender,
